I have a PS3 , Acer H5360 and the nVidia 3D vision kit with a new video card on the way ( should get that today). Can I play ps3 games in 3D with that setup or do I have to get something else for the PS3?

I found an old post from few years ago that mentioned Optoma 3D-XL kit and thought I read something about a monoprice kit but I would like to know if that is still necessary.

you can use the nvida kit with a PC connection but not the PS3.
You need a 3d-xl or the like to get a 3d image out of the ps3.
I personally have a Viewsonic vpl3d device which sits in between my 5360 and my ps3 -- has worked flawlessly for the last year.

Now that I think of it, there was an old trick where if you ran the Nvidia 3D test loop on your PC, the 3DVision glasses would sync with a Mitsubishi DLP HDTV and a PS3. I need to try it with the super big screen some day when I'm bored to see if it still works.
